。During treatment, if the powder is difficult to wet with the silicic acid alkali metal salt bath solution or difficult to disperse when finely divided using a dispersion machine, a small amount of surfactant may be added to further improve the effect. Heating may be performed during stirring and mixing to increase the temperature.
（作用ン
本発明に係る２表面にケイ酸のアルカリ金属塩を吸着処
理した粉体が、水に対して濡れ易く。(Action: 2) The powder according to the present invention, whose surface has been treated with adsorption of an alkali metal salt of silicic acid, is easily wetted by water.

覆することにより、粉体の表面の親水性が増大するため
と考察される。In addition, although it is not certain whether the powder has the property of being difficult to settle, the alkali salt of silicic acid is adsorbed onto the surface of the powder.
It is considered that this is because the hydrophilicity of the surface of the powder increases by inverting the powder.
